Best Smart Plugs UK 2026 — Save Money on Energy Bills with Monitoring

The TP-Link Tapo P110 is the most popular energy-monitoring smart plug in the UK for good reason. The Tapo app shows real-time wattage, daily and monthly kWh consumption, and can calculate actual cost based on your energy tariff — a genuinely useful feature when you're trying to identify which appliances are draining your budget. Scheduling is straightforward: set your electric heater to turn off an hour before you leave for work, or put your phone charger on a timer so it doesn't draw standby power overnight. Voice control works with both Amazon Alexa and Google Home, and the compact Type G design doesn't block the adjacent socket. At £13, it pays for itself after identifying just one energy-wasting habit.

• Pros: Real-time energy monitoring with cost tracking, Alexa and Google compatible, compact UK plug
• Cons: No Apple HomeKit support, requires TP-Link cloud account for remote access

If energy monitoring isn't your priority and you simply want to automate multiple appliances, the Meross 4-pack is extraordinary value at £29 — that's under £7.50 per plug. All four support Alexa, Google Home, and Apple HomeKit, which is rare at this price point and means they work whatever smart home ecosystem you're running. Scheduling and timer functions are reliable and easy to set up in the Meross app. Common use cases: scheduling a lamp to turn on at sunset, cutting standby power to the TV when you go to bed, or turning on a fan on a schedule. No energy monitoring is the main trade-off — if that's important, step up to the Tapo P110.

• Pros: Best value per plug, Alexa + Google + HomeKit support, reliable scheduling
• Cons: No energy monitoring, app is functional but not polished

If you already have an Amazon Echo in the house and want the simplest possible smart plug setup, the Amazon Smart Plug is the answer. Plug it in, say "Alexa, discover devices" and it appears in the Alexa app automatically — no third-party app, no account creation, no QR code scanning. For older family members or anyone who finds app-heavy smart home devices frustrating, this frictionless experience is worth the slight premium over cheaper alternatives. Voice control is instant and reliable. Scheduling through the Alexa app is straightforward. No energy monitoring, but for basic automation it's the most hassle-free option in this guide.

• Pros: Instant Alexa pairing, no separate app required, dead-simple setup
• Cons: Alexa-only (no Google or HomeKit), no energy monitoring, bulkier than rivals

The Eve Energy is the premium choice for iPhone and Apple Home users who take privacy seriously. Unlike most smart plugs that route all data through a manufacturer's cloud server, Eve processes everything locally on your home network using Apple's HomeKit Secure Router framework — your usage data never leaves your home. The Thread protocol (supported by Apple HomePod mini and newer Apple TV 4K) makes the connection faster and more reliable than Wi-Fi-based alternatives. Energy monitoring is included and integrates cleanly into the Eve app and Apple Home. At £39 it's the priciest option here, but for Apple households who want reliable, cloud-free automation with accurate energy data, it's the right buy.

• Pros: Local processing (no cloud), Apple HomeKit + Thread + Matter, precise energy monitoring
• Cons: No Alexa or Google Home support, premium price, requires Apple Home for full features
